Ethyl cellulose solubility na acetone

Ethyl cellulose solubility na acetone

Ethyl cellulose bụ polymer a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, na nlekọta onwe onye. A maara ya maka ihe ndị na-emepụta ihe nkiri dị mma, nkwekọ dị elu na ihe ndị ọzọ, na ezigbo iguzogide kemịkalụ na ihe gburugburu ebe obibi. Otu n'ime ihe ndị bụ isi nke ethyl cellulose bụ solubility ya, nke nwere ike ịdịgasị iche dabere na ihe mgbaze eji.

Acetone bụ ihe mgbaze nkịtị nke a na-ejikarị na-emepụta ihe nkiri ethyl cellulose na mkpuchi. Ethyl cellulose bụ nke soluble na acetone, nke pụtara na ọ nwere ike igbari ruo n'ókè ụfọdụ mana ọ nwere ike ọ gaghị agbaze nke ọma. Ogo nke solubility nke ethyl cellulose na acetone na-adabere n'ihe dị iche iche dị ka ịdị arọ molekụla, ogo nke ethoxylation, na ntinye nke polymer.

N'ozuzu, ethyl cellulose dị arọ nke dị elu na-emekarị ka ọ ghara ịdị nro na acetone ma e jiri ya tụnyere ethyl cellulose dị arọ molecular. Nke a bụ n'ihi na polymer dị arọ nke dị elu nwere ogo dị elu nke polymerization, na-eme ka usoro dị mgbagwoju anya na nke siri ike na-eguzogide ọgwụ na-eguzogide ọgwụ. N'otu aka ahụ, ethyl cellulose na ọkwa dị elu nke ethoxylation na-emekarị ka ọ ghara ịdị nro na acetone n'ihi ụba hydrophobicity nke polymer.

Mbelata nke ethyl cellulose na acetone nwekwara ike imetụta ntinye nke polymer na ihe mgbaze. N'ebe dị ala, ethyl cellulose nwere ike ịgbaze na acetone, ebe n'ogo dị elu, solubility nwere ike ibelata. Nke a bụ n'ihi n'eziokwu na n'ọtụtụ dị elu, ụmụ irighiri ihe ethyl cellulose na-emekọrịta ihe na ibe ha, na-emepụta netwọk nke ụdọ polymer nke na-esighị ike na ihe mgbaze.

Enwere ike ịkwalite solubility nke ethyl cellulose na acetone site na mgbakwunye nke ihe mgbaze ndị ọzọ ma ọ bụ plasticizers. Dịka ọmụmaatụ, mgbakwunye ethanol ma ọ bụ isopropanol na acetone nwere ike ịbawanye solubility nke ethyl cellulose site na imebi mmekọrịta intermolecular n'etiti ụdọ polymer. N'otu aka ahụ, mgbakwunye nke plasticizers dị ka triethyl citrate ma ọ bụ dibutyl phthalate nwere ike ịbawanye solubility nke ethyl cellulose site n'ibelata ike intermolecular n'etiti ụdọ polymer.

Na nchịkọta, ethyl cellulose bụ akụkụ nke soluble na acetone, na solubility ya nwere ike ịdịgasị iche dabere n'ihe dị iche iche dị ka ịdị arọ molekụla, ogo nke ethoxylation, na ntinye nke polymer. Enwere ike ịkwalite solubility nke ethyl cellulose na acetone site na mgbakwunye nke ihe mgbaze ndị ọzọ ma ọ bụ plasticizers, na-eme ka ọ bụrụ polymer dị iche iche maka ojiji na ngwa dị iche iche.
